This paper studies the identification of construction hazards of operating conditions , accident type and construction division of the evaluation unit , discusses the working conditions and improved risk assessment methods through research hazard identification and accident type , so as to identify the inherent construction or potential risk factors for the design , construction and management to provide theoretical guidance and technical data , has important scientific significance and value of work . Defects in the existing operating conditions for the risk assessment method to get perfect complement to improve the safety evaluation methods. The risk of operating conditions to determine the risk evaluation method exists than the original LEC method , L values ??more scientific and feasible , enhance economic security through an amendment to put L item, use the system to control the relationship between energy and human energy sex . Finally, this paper summarizes and prospects for future work were Keywords : Construction hazard The accident types The work condit
